How to design a successful embolic protection devices clinical trial

Embolic protection devices could reduce risks of interventional cardiac procedures such as TAVR, but their efficacy is hard to prove. David Novotny, Novella Clinical The embolic protection device (EPD) market is expected to grow into a billion-dollar industry if the device becomes the standard safety protocol for transcatheter aortic valve replacement (TAVR) and other interventional

Fluoropolymer medical tubing: What you need to know

Here are some important considerations when it comes to extrusion equipment and safety related to processing fluoropolymer medical tubing. Steve Maxson, Graham Engineering Corp. Medical tubing processors are showing more interest when it comes to venturing into the world of fluoropolymers – and for good reason. Materials such as FEP, PFA, PVDF and ETFE are

Nexus IE creates catheter coating test system for BioInteractions

Product consultancy Nexus Intelligent Engineering (Nexus IE) has designed and developed a fully automated catheter coating test system for medical device coatings supplier BioInteractions. Nexus IE (Witchford, U.K.) designed the BIOFriC 1000 fto measure the coefficient of friction of coated catheters. The test system could have uses in both  medical R&D laboratories and product manufacturing

How to ensure adhesion on hard-to-bond plastic substrates

Medical device companies are increasingly using plastic substrates that are tough and sterilization/chemical resistant. But they also come with adhesion challenges. Michelle Gumbert and Patrick Vaughn, Dymax  For medical devices such as catheters, prefilled syringes, vials, test tubes and injector pens, many manufacturers are turning to plastic substrates that are specifically formulated to resist harsh

Abbott’s new contact ablation catheter: Here’s what you need to know

The new TactiCath contact ablation catheter unites EndoSense and St. Jude Medical technologies that Abbott acquired, marrying fiber optics, flexibility and 3D mapping. If you want your grilled cheese to cook faster, you press it into the pan with your spatula. That’s contact force, the principle behind Abbott’s TactiCath contact force ablation catheter, according to

Avinger shares slide on Q2 miss

Shares in Avinger (NSDQ:AVGR) fell today after the medical device developer missed expectations on Wall Street with its second quarter earnings results. The Redwood City, Calif.-based company posted losses of $12.8 million, or 54¢ per share, on sales of $2.5 million for the 3 months ended June 30, seeing losses shrink 5.2% while sales shrunk 47.5% compared

Medtech stories we missed this week: August 4, 2017

From MDCorp inking a European distribution deal to Align Technology’s North Carolina expansion, here are seven medtech stories we missed this week but thought were still worth mentioning. 1. MDCorp inks distribution deal with Smart Endoscope Systems MDCorp announced in a July 31 press release that it has signed a distribution agreement with Smart Endoscope

Freudenberg Medical spends $10M to expand Irish catheter plant

Freudenberg Medical today announced that its VistaMed joint venture company has spent €9 million, equivalent to about $10 million, expanding its Carrick-on-Shannon, Ireland catheter manufacturing facility. The expansion added 45,000 square feet – including four additional ISO Class 7 cleanrooms – to VistaMed’s existing plant in Carrick-on-Shannon. The project enables VistaMed to better meet demand when it

The ins and outs of microextruded medical tubing

Microextruded medical tubing could enable increasingly smaller surgical and home care products, according to Tekni-Plex’s Natvar.  Surgical and home care products including catheters are becoming increasingly complex and smaller in size. Neurovascular interventional therapies and surgical procedures also require tight tolerances for those small sizes. Until now, options for these components were limited to glass

Clever catheter lets surgeons see inside arteries to trim plaque

The Pantheris catheter developed by Avinger takes the physician out of the radiation field. A clever catheter design lets cardiologists see inside arteries and precisely remove plaque from diseased tissue. The Pantheris catheter is safer than conventional radiation-guided procedures because it takes the surgeon out of the radiation field, and along with on-board optics, it

Researchers create ‘ultrasound drill’ to attack thrombosis

North Carolina researchers have developed a new surgical tool that uses low-frequency intravascular ultrasound to break down blood clots that could cause deep vein thrombosis. The ultrasound “drill”, called that because it can be aimed directly ahead, could allow physicians to better target clots and reduce treatment time, according to researchers from North Carolina State

Abbott’s MitraClip can be implanted through the jugular vein, too

A Canadian cardiologist has successfully inserted Abbott Labs’s MitraClip through the jugular vein instead of the femoral vein, according to a recent report. Dr. Neil Fam inserted the Abbott Laboratories device into an 86-year old patient with severe mitral regurgitation. Because of the patient’s age, traditional surgery to repair her mitral valve was not an

What is catheter (PTCA) treatment?

Asahi Intecc Catheter treatment (percutaneous transluminal coronary angioplasty, or PTCA, treatment) is one of the methods of treatment for diseases such as angina pectoris and myocardial infarctions that are caused by the heart’s blood vessels (coronary arteries) becoming clogged or narrowed by cholesterol. Previously it was common to treat such diseases with medication or, if

Covalon Technologies launches new coating for intravascular devices

Covalon Technologies has launched its new Centaur low particulate, lubricous coating for intravascular medical devices including catheters, guidewires and delivery sheaths. Centaur is designed to improve the safety and functionality of intravascular medical devices to prevent significant patient complications that arise from the presence of unwanted particulates. Covalon’s new coating was studied in a third

Navtar expands medical tubing portfolio

Natvar, a Tekni-Plex company, has launched thermoplastic microextrusion tubing. The technology is used in neurovascular interventional therapies and surgical applications. Microextrusion tubing offers a replacement for glass and fluoropolymers, and the company promises short development lead time. The new tubing option could help drive innovation in these therapeutic spaces. Microextruded options include monolayer, coextruded, multi-lumen tubing or profiles
